Hi @davele739,

Unfortunately, we were unable to reproduce the issue. The IP address detected in the Torrent Address detection is not the same as the selected VPN location. However, this is because torrent traffic is redirected to a different server, and the detected IP does not represent the real client IP address.

We kindly ask you to try installing the latest Nightly version of AdGuard VPN and check if the issue is still reproducible. If this is the case, please send us the app logs. Here's what we need you to do:

Go to Settings → App settings → Logging level → Record everything;
Reproduce the problem and remember the exact time it was reproduced at. We will need it to find the corresponding entries in the log file;
Open Support tab → Export logs and system info;
Send the archive to devteam@adguard.com and mention this issue number in the subject. Don't forget to include the time of reproduction.
Set the logging level back to Record by default.

Please let us know of the results, regardless of the outcome.

I understand. I resolved the issue by binding my torrent client to AdGuard VPN and disabling WebRTC, preventing any IP leaks. To confirm, I also downloaded Transmission (another torrent client) and verified that my actual ISP-provided IP address was not revealed while torrenting. This confirmed that the issue I previously experienced with qBittorrent was indeed with the torrent client itself, not the VPN.Thank you for confirming that others are not experiencing this issue. It helped me rule out any problems with my device or setup.
